Excellent customer service




Review of Mike Diamond Plumbing, Inc.

Cesar and John didn't waste anytime and git right to work cleared my kitchen line. Then they went to the extra mile and went under the house to inspect the condition of my pipes to give me a better understanding of it what's goin on down there. If I have any other problems I know who I am calling.
